The relationship between size of cerebral ventricles in chronic schizophrenics and performance on a comprehensive neuropsychological battery, the Standardized Luria-Nebraska Neuropsychological Battery, was investigated. Ventricular size was determined by using a planimeter to measure the size of the lateral ventricles and the ventricular body, if present,(More)
This article investigates the adequacy of the Heaton-Grant-Matthews norms in correcting age and education effects in the Halstead Reitan Neuropsychological Battery. Two hundred and ninety neurological and 346 psychiatric patients were administered the Halstead Reitan Neuropsychological Battery. Raw scores were converted to standard scores using the(More)
We examined relationships between demographic and diagnostic variables and Benton Visual Retention Test performance in older adults aged 55 to 97 years. We derived extended geriatric norms for BVRT total number correct scores adjusted for variables that contributed significantly to the variance. We also investigated BVRT performance in two commonly(More)
The study compared 5 patients with recently diagnosed Huntington's Disease with 8 patients whose onset was between 36 and 66 months prior to testing, 6 patients whose onset was greater than 72 months previous, and 7 control patients equated for age and education. The results showed evidence of focal damage in the early group on two scales of the(More)

Characterizing a pattern of cognitive dysfunction in early onset schizophrenic patients may illuminate neurodevelopmental contributions to the illness. A cohort of chronically institutionalized schizophrenic patients with a variable range of age of onset (range 7-29 years) was administered a comprehensive battery of neuropsychological tests that included(More)
The present study examined the ability of the Mini-Mental State Examination (MMSE), a cognitive screening test commonly employed in research and clinical applications, to predict level of performance on a comprehensive neuropsychological battery, the Luria-Nebraska Neuropsychological Battery (LNNB). The tests were administered to a diagnostically mixed(More)
Serum cortisol concentrations were measured after dexamethasone administration (1 mg) in 21 neuroleptic-free schizophrenic inpatients. Patients were assessed using the Brief Psychiatric Rating Scale and a battery of cognitive tests. A significant correlation was found between negative symptoms and both 8:00 AM and 4:00 PM post-dexamethasone cortisol(More)
